Subject About lucene memory consumption
Date Fri, 27 Jun 2014 08:42:07 GMT
Hi, all


   I fould that the memory consumption of ‍my lucene server is abnormal, and “jmap -histo
${pid}” show that the class of byte[] consume almost all of the memory. Is there memory
leak in my app? Why so many  byte[] instances?
‍
 






The following is the top output of jmap:‍


 num     #instances         #bytes  class name
----------------------------------------------
   1:       1786575     1831556144  [B
   2:        704618       80078064  [C
   3:        839932       33597280  java.util.LinkedHashMap$Entry
   4:        686770       21976640  java.lang.String‍

Thanks & Best Regards!
